Also on backgrounds, there is a new tip at Blendercookie on how to map background images to empties (using 2.58) which allows you to view the images from any angle. A much better method if working from blueprints and the like instead of just reference photos.

Also, if you're having trouble with the mouse right click selection method in Blender, this can be changed to Left click selection through the user preferences.

 Also remember that if you are used to a particular programs shotcut keys, these can also be mapped through user preferences and saved as a new keyset.
